USB PD 3.1 high-voltage MCU with higher wattage support
Infineon Technologies has introduced the industry’s first high-voltage microcontroller (MCU) with USB Power Delivery (USB PD) 3.1 support.
The EZ-PD PMG1 (Power Delivery Microcontroller Gen1) is Infineon’s first generation of USB PD MCUs targeting any embedded system that provides or consumes power with high-voltage up to 28 V (140W).
The device is able to support higher power capabilities defined in the USB PD 3.1 specification and leverages the MCU to provide additional control capability. The products are intended for consumer, industrial and communications markets for applications such as smart speakers, routers, power and garden tools.
The PMG1 family integrates a USB PD stack to enable reliable performance and interoperability. It features an Arm Cortex-M0/M0+ processor with up to 256 KB Flash memory and 32 KB SRAM, USB full-speed device, programmable general purpose input/output (GPIO) pins, gate drivers, low drop out (LDO) regulators and high-voltage protection circuits.
The PMG1 MCU also provides hardware and firmware protection, including over-voltage and over-current protection, short circuit and reverse current protection, secure firmware boot and signed firmware update.
Enhancing the ease-of-use for designers, the devices include programmable analogue and digital blocks simplifing customisation and integration of intelligent analogue sensors into the application.
The PMG1 MCU is also field programmable to allow signed firmware updates for improved efficiency. Programming is supported by the ModusToolbox integrated development environment with the PMG1 software development kit along with prototyping kits and quick start guide – making the firmware development and testing simple and easy to further reduce the overall development time and time-to-market.
